Toxin-producing cyanobacterium Nodularia spumigena

In: Journal of Experimental Marine Biology and Ecology. 2004 ; Vol. 308, No. 1. pp. 85-101.

The toxicity of NODs is due to the severe inhibition of the protein phosphatases 1 (PP-1), 2A (PP-2A), and 3 (PP-3), which leads to functional disturbance and structural disruption of the liver ( Chen etal.,2013a; Luckas etal.,2005 ). 2015-11-01 The results indicate that the round goby (Neogobius melanostomus) exposed to extracts from N. spumigena cells triggered a defense system in a time-dependent manner. The obtained results contribute to a better understanding of fish response to the presence of compounds produced by N. spumigena. 2005-01-01 2002-12-03 N. spumigenawas characterized by a stronger allelopathic activity than Synechococcussp., showing a negative effect on all target species. The highest decline in growth, as well as the most apparent cell physical damage, was observed for the diatom S. marinoi. In the presence of ammonium ion, Nodularia spumigena strain AV1, a filamentous, heterocystous cyanobacterium isolated from the Baltic Sea, lost aerobic nitrogen-fixation activity while maintaining heterocyst frequency along the filaments. A clonal isolate, termed L575, of the filamentous brackish-water cyanobacterium Nodularia spumigena Mertens emend.

In this study, effects of Nodularin (NODLN), a cyclic pentapeptide hepatotoxin, on liver and gill tissues of A. persicus were studied. Nodularin was produced in high amounts by Nodularia spumigena, a cyanobacterium species during the algal bloom in … Vintila S, Wadensten H, Nilsson A, Andrén PE, El-Shehawy R (2010) Proteomic profiling of the Baltic Sea cyanobacterium Nodularia spumigena strain AV1 during ammonium supplementation.

Oct 30, 2015 The ecological consequences of the blooms include changes in the physical and chemical conditions of aquatic ecosystems and the direct and We investigated the allelopathic effects of three cyanobacterial species ( Nodularia spumigena, Aphanizomenon flos-aquae and Anabaena lemmermannii ) that spumigena populations, especially in the Baltic Sea, we have investigated the effect of nitrate and ammonium ions on growth , nitrogen fixation activity and May 25, 2016 of nodularin in South Atlantic coastal waters with consequences to cyanobacterial (Nodularia spumigena) growth leading to a decrease on. Comparative effects of the blue green algae Nodularia spumigena and a lysed extract on detoxification and antioxidant enzymes in the green lipped mussel Nodularia spumigena is one of the dominant toxic cyanobacteria which produce blooms in the Baltic Sea, a brackish water body, particularly in late summer. Sep 13, 2016 (Anguilla australis): potential consequences for human consumption centuries. This lake experiences blooms of Nodularia spumigena.

trutta L.) were exposed orally to a single dose of food containing NODLN (125 mg/kg ww) from N. spumigena (strain AV1, from the Baltic Sea). Nodularia spumigena är en regelbundet återkommande art i Östersjöns planktonsamhälle under sommaren och kan ställa till stora problem i samband med algblomning. Algen producerar toxinet nodularin, vilket kan vara skadligt för både människor och djur. Nodularia spumigena kallas även katthårsalg, då den ser ut som grönt katthår. We investigated the effects of addition of dissolved organic matter (DOM) on the growth and chemical composition of Nodularia spumigenacells under conditions of P or N deficiency.
